Stanislaw was arrested Saturday after allegedly firing into a home while “hunting zombies” at around 5 a.m. in North St. Paul, Minnesota, Fox 9 News reports. Police say a bullet from an AR-15 rifle shattered the window of Ken Quaale, who was asleep at the time.

Luckily, the bullet narrowly missed Quaale’s head, ricocheting off the walls of his bedroom, he said.

Stanislaw, 24, allegedly told police he was simply out “making sure my neighborhood is safe” and that he was aiming at “a zombie.” He was also carrying bullets marketed as anti-zombie ammunition.

A criminal complaint cites Stanislaw’s mother as saying he has no history of mental illness, CBS Minnesota notes. He was charged with a firearm violation, as well as the possession of a firearm by an ineligible person, according to Ramsey County arrest records. Stanislaw was considered ineligible because he was convicted last month of making terroristic threats.
